This technology uses Bluetooth sensors and a mobile app to track and control access of personnel, students, and visitors at educational and social institutions. It deploys a Bluetooth sensor network using Bluetooth 4.0 technology. A mobile app registers a visitor's movement and allows automated access to specific services. The system includes a positioning server that processes requests from sensors to calculate zones and recognize IDs to determine a device's position for access control.

2. Abstract
The technology controls personnel, student and visitor
movement at educational and social institutions. It implies
sensor network deployment on the base of Bluetooth 4.0
BLE technology.
Special application installed on a visitor's smartphone registers
movement across the given territory and allows to get automated
access to specific services (access to enclosed space, literature
from the library, lunch, etc.).
Original network protocols involve bootstrapping modules considering
network topology, distance to the nearest node and device operating
mode.

3. Management system structure
and the principles of operation
The server processes
the requests received
from transmitters in the
access cell. Afterwards
the application calculates
the zone radii where
the identification objects
are located at a given
time, and recognizes
them according
to hardware addresses
(MAC-addresses).

The addresses are
registered when

and are stored
in a database
server for some
time.

5. Location determination algorithm
1. Each stationary Bluetooth device searches for Bluetoothactive mobile customers with a given frequency.
2.
As the client accesses the area of a base unit it connects
with the unit by Bluetooth and server receives the device
address and data.
3.
The server part of the program complex processes the data
received and checks the address according to a proper
permission.
4.
In case your mobile device has not passed the registration
procedure upon the entrance to the access zone,
MAC-address is filtered and device will not be permitted
to transfer control actions and to implement various
management scenarios.

6. Location determination algorithm
5.
After identification the program analyzes the data received
and compares it with the data of specific access areas
defined by the relevant range.
6.
Afterwards the application determines the approximate
location of a particular mobile device relative to
a stationary base unit.
7.
After the initial locating determination, during its movement
within the stationary base zone, the zone boundaries
are shifted by a predefined step depending on the way
the signal level changes.
